LAMP-SHADE SUPPORT:

Application filed March 18,1923. Serial No. 624,851.

To all whom it may concern:

Be it known that we, WALTER C. Gnnrsr, ANoenw J. Canarrcrnucs, and Jon)?1 12-. runs .z-r, citizens of the United States of America, residing atNew Haven, in the county of New Haven and State of'Con-= necticut, haveinvented certain new and. useful Improvements in Lamp-Shade Supports,ofwliich the following is a full, clear, and exact description. i i

This invention relates to shade-supporting means for electric and otherlamps, whereby the shade maybe supported reli-' ably at various angleswith reference to the lamp bulb.

An important. feature of the invention comprises an improved form ofclamping device to engage the bulb, and which is constructedtoreliablysupport the shade from and by the use of an economical constructionwhich may be manufactured in large quantities, and ata relatively smallcost.

In connection with the clamping device, the invention contemplates theuse of a universal joint or connection between said device and the lampshade, the construction of which is such that the shade maybe tilted atvarious angles tothe longitudinal axis of i the bulb and will bereliably maintained in any of the-positions of adjustment to which itmay be set;

Other important features of the invention, such as valuabledetails ofconstruction and combinations of parts, will be better understood fromthe following description in connection with the accompanying draw ings,and the novel features of the invention will be pointed out in theappended claims:

Fig. 1 represents a lamp shade in section, and the improved shadesupporting device in side elevation;

Fig. 2 is a view in elevationof the shade support taken at right anglesto the position in which said support is illustrated in Fig. 1, and pFig. 3 is an inverted plan View of Fig. 2.

Referring to Fig. 1, the shade 3 is provided at its central top portionwith a hole through which passes a threaded stem 5 which extends from asplit member 6 of the universal joint comprising the members 6, 7, and8. A shoulder on-the member 6 bears against a metal washer9 within theshade the bulb in a simple and efiicientmanner,

and having a hole in alignment with the hole in the shade through whichpasses the stem 5,'and a knob 10, provided with an internal thread toengage the stem 5,, serves to clamp the member 6 and washer firmly. tothe. lamp shade.

as an ornamental featurethereof.

. The member. 7 of the universal joint is preferably formedfrom a singlepiece of sheet metal, having two parallel limbs 11, 11, which embracethe split member 6 of the joint and are connected thereto by a suitablerivet 12 which is preferablywheaded" at Said knob is located at, thetop,.central portion of theshade and serves both extremities on theoutside of the limbs 11, 11. Two limbs 13, 18, which extend away fromthe limbs 11, 11, and which are bent along lines extending-at rightangles to the lines on which the limbs 11, 11, are bent are connected bya pivot 14- With a split member 15. The member 15 of the universal jointhas'rigid connection, as by a1 rivet,

constitute the shade support proper-u The member 16 of. theshade supporthas a flat portion 20 from whichthe arms a, a, are

bent downwardly and outwardly and terminute at their lower ends incircular clamps 21, 21. flat portion overlying the-flat portion of themember 16, andhas also two 1 downwiththe twocrossed members '16., 17,which The member 17 is provided with a wardly and outwardly inclinedarms 6, b, I

likethe arms a, a, but arranged at right angles to the latter. a Thearms I), b, also terminate in circularportions 22, 22, forming clampswhich are located between the circular clamps 21, 21, of the member 16.four circular clampmg members 21, 21, and

22,22, are arranged, as will appear from.

Fig. 1, approximately fapart and serve to engage the lamp bulb B. uponfour sides,

The

position upon the bulb and is more reliable in this respect than a coilof wire or any other form of metal clamp which has'less positive holdingpower than the circular formation. At the same time, the circularclamping members may be stamped out of sheet metal with ease, and by theuse of simple dies, the material employed in such form of clamprendering it possible to manufacture the device in quantities at aminimum expense. If it be desired to tilt the shade 3, relathe clampingmembers and the bulb B which should be that shown in Fig. 1 of thedrawlngs.

lVhile advantageousresults have been 'found to follow from theemployment of two pairs of clamping members,"as l6, 17, eachprovidedwith two circular clamps, as shown herein, certain benefits ofthe invention have been found to follow from the use of three circularclamps,instead of four. It is also within the contemp'lationot theinvention to form the crossed members 16,

17, of a single piece ofmetal instead of two pieces, and in someinstances this modification has been found to give very good results.The invention is, accordingly,- not necessarily limited to the exactdetails of construction and arrangement of parts shown herein, but maybe varied in the respects noted, and otherwise, so long as suchvariations fall within the scope of the following claims.

What we claim is new and desire to secure by Letters Patent is:

1. A lamp shade support made of fiat sheet material, and comprising aplurality of clamping arms arranged angularly to each other, said armsterminating in circular clamping members to engage a lamp, with meansfor securing said support to a shade.

2. A lamp shade support made of sheet material, and comprising twomembers arranged at right angles and provided with with said support andat its other terminal with a lamp shade, said joint being capable ofmovement to'permit said shade to be adjusted at varying angles to theaxis otthe lamp without causing said support to move from normal lampengaging-position;

4. A lampshade support comprising, in combination, a sheet metal memberhaving a perforated fiat portion with a plurality of downwardlyextending diverging arms terminating in completely circularlamp-engaging portions, and a flexible joint having rigid connectionwith said flat portion at one end; the other end of said joint beingsecured to a lamp shade.

In'testimony whereof we have hereunto set our hands this 15th day ofFebruary A. D. 1923.
